Title: Orthopedic system having detachable bone anchors
Inventor: SELLERS TIMOTHY M
IPC: A61B17/00
Filed: 2000-03-09
Abstract: The present invention provides an improved orthopedic system in which the part of the device that attaches to the bone is detachable from the parts of the device which provide the bone stabilization, distraction, etc. In a preferred embodiment, the system includes a proximal bone plate (14) and associated proximal fastener (18), and a distal bone plate (16) and associated distal fastener (20). The bone plates (14;  16) are affixed to the bone on opposing sides of the bone repair site, which may be an osteotomy. The fasteners (18; 20) serve to mechanically couple the orthopedic device, which may be a distractor, through the bone plates (14; 16), to the bone. The fasteners (18; 20) are releasably mechanically coupled to the bone plates (14; 16). This releasability permits the distractor and fasteners (18; 20) to be removed after the orthopedic procedure is complete, leaving only the bone plates (14; 16) in the patient. The bone plates (14;  16) may be made with a low profile, such that they may be left permanently in the patient. In a preferred embodiment, the bone plates (14; 16) are made from a resorbable material, such that they will be absorbed by the patient's body.  Methods for using this novel orthopedic system are also disclosed.

Title: Methods for producing modified glycoproteins
Inventor: GERNGROSS TILLMAN U
IPC: C12N15/09
Filed: 2001-06-27
Abstract: Cell lines having genetically modified glycosylation pathways that allow them to carry out a sequence of enzymatic reactions, which mimic the processing of glycoproteins in humans, have been developed. Recombinant proteins expressed in these engineered hosts yield glycoproteins more similar, if not substantially identical to their human counterparts. The lower eukaryotes, which ordinarily produce high-mannose containing N-glycans, including unicellular and multicellular fungi are modified to produce N-glycans such as Man5GlcNAc2 or other structures along human glycosylation pathways. This is achieved using a combination of engineering and/or selection of strains which:  do not express certain enzymes which create the undesirable complex structures characteristic of the fungal glycoproteins, which express exogenous enzymes selected either to have optimal activity under the conditions present in the fungi where activity is desired, or which are targeted to an organelle where optimal activity is achieved, and combinations thereof wherein the genetically engineered eukaryote expresses multiple exogenous enzymes required to produce "human-like" glycoproteins.

Title: Providing secure network access for short-range wireless computing devices
Inventor: GOPAL AJEI SARAT
IPC: G09C1/00
Filed: 2001-08-27
Abstract: Methods, systems, and computer program instructions for providing location-independent packet routing and secure access in a wireless networking environment (such as that encountered within a building), enabling client devices to travel seamlessly within the environment. The secure access techniques provide user-centric authentication and allow policy-driven packet filtering. A client authentication module (1405) is integrated into the client (1400), and a server authentication module (1425) is integrated into the access point (1420). The client authentication module communicates (1415) with the server authentication module to provide the user's authentication credentials (e.g. user name and password). Once the user is authenticated (1445), by means of an authentication server (1450) using techniques of the prior art, the server authentication module and the client authentication module negotiate a session key to enable link-level encryption. This link-level encryption takes advantage of the encryption capabilities embedded in the client and access point hardware (1410, 1430).
